Same error here since yesterday. Such a bummer. 

Will it be okay or just finished with adobe express 🤣?

I tried everything, I used 3 cell phones, 2 computers, I tested it on several internet providers, I also tried using an incognito window, I even asked my friends from other cities to try animating the character with their voices, and yet the error persists.

Experiencing the same issue and did all that was listed with no help.

Please advise...
